Using the noise canceling function
Set the NC switch to ON.
The indicator lights up in green.
Setting the NC switch to OFF turns off the noise canceling function. (The indicator light goes out.)
Using the noise canceling function mainly helps to reduce ambient noises such as noise in a vehicle and noise from air conditioners in a room.
In addition to using the noise canceling function when listening to music, you can also use the function alone.
This unit cannot guarantee operation of all of the remote control functions.
When the remaining battery power becomes low, an alarm will sound every 4 minutes.Charging
The noise canceling function is effective for low-pitched sounds such as noise in a vehicle and noise from air conditioners in a room but less effective for relatively high-pitched sounds such as announcements, conversations and bells in vehicles.
Turn off the noise canceling function after using to avoid draining the battery.
